PARAMETERS
insname Name of the instance in the which the reference is to be searched for
refname Name of the reference to be used for the segment placement
layer Physical layer of the segment
width Width of the segment
face Face of the figure on which the segment is to be placed
DESCRIPTION
PLACE_SEG_REF places a segment regarding the position of the reference, refname, in the instance called insname. The segment coordinates
are computed from the reference coordinates and the face given as argument.
Two behaviours are expected, regarding the reference coordinates:
the reference is on the given face of the abutment box
the segment is not added, since it would have zero as length
the reference is anywhere else
A segment is drawn between the reference and the abutment box, and is given layer and width as attributs. One of its
endpoint is given by the reference coordinates, the other one comes from the face. The face argument is meant in the
placed instance, and can take any of the following values:
NORTH the other endpoint has, for absissa, the x coordinate of the top of the abutment box of the cell, and for ordinate, the
y coordinate of the reference.
SOUTH the other endpoint has, for absissa, the x coordinate of the bottom of the abutment box of the cell, and for ordinate,
the y coordinate of the reference.
EAST the other endpoint has, for absissa, the x coordinate of the reference and for ordinate, the y coordinate of the right
of the abutment box of the cell.
WEST the other endpoint has, for absissa, the x coordinate of the reference and for ordinate, the y coordinate of the left
of the abutment box of the cell.
ERRORS
"GENLIB_PLACE_SEG_REF impossible : missing GENLIB_DEF_PHFIG"
No figure has been yet specified by a call to DEF_PHFIG. So it isn't possible to place a reference inside it. you must call
DEF_PHFIG before any other layout action.
"GENLIB_PLACE_SEG_REF impossible : missing GENLIB_DEF_PHFIG"
No figure has been yet specified by a call to DEF_PHFIG. So it isn't possible to place a reference inside it. you must call
DEF_PHFIG before any other layout action.
"GENLIB_PLACE_SEG_REF impossible : no abutment box"
The current figure does not have an abutment box. Use DEF_AB(3) before this function.
"illegal GENLIB_PLACE_SEG_REF : orientation is XX"
The face parameter does not have a legal value, but XX.
"illegal getphins : instance called insname does not exist"
No instance called insname exists in the current figure
"illegal getphref : references called refname does not exist"
No reference called refname exists in the model of the instance insname.
EXAMPLE
#include <genlib.h>
main()
{
/* Create a figure to work on */
GENLIB_DEF_PHFIG("cell");
GENLIB_PLACE("gaci0_b", "r1", NOSYM, 23L, 54L);
/* Put a reference */
GENLIB_PLACE_SEG_REF("r1", "a_0", ALU2, 2, NORTH);
/* Save that on disk */
GENLIB_SAVE_PHFIG();
}
